I'm trying to isolate the source of the problem. I know it can't be a driver error because it's not a USB. Because it's a jack one (green+pink), the problem must be my audio card (Guessing it's built-in my laptop?). Then again, that couldn't be my problem because my built-in microphone works perfectly.
That being said, only possible problem would be that I somehow muted my microphone but I've checked literally everything...
And I still don't get why it says it's not plugged in when it is, unless it's not talking about my headset...
